A 'greedy' bear which mauled a man has been taken to a 'fat camp' today, with officials saying he was overweight with an eating problem.

Eight-year-old bear Bing was attacked Naiphum Promratee, 36, who had been teasing him by dangling rice in his jaws on Wednesday morning.

His keepers in Thailand want to change Bing's behaviour, claiming he is 'very, very fat' because visitors keep on feeding him.

Keepers in Thailand want to change Bing's behaviour, claiming he is 'very, very fat' because visitors keep on feeding him

The eight-year-old bear attacked Naiphum Promratee, 36, who had been teasing him by dangling rice in his jaws on Wednesday morning

The 250kg animal has been described as having a good temperament, but 'greedy'.

Bing grabbed Naiphum's arm and pulled him over a concrete barrier. He then pinned Naiphum to the ground before dragging him with his teeth into his cage and starting to eat him - tearing a lump from his ribs under his armpit.

Friends eventually raced into the enclosure and battered Bing with a metal bar to free the horrifically injured man.

The bear was today shot with tranquilliser darts and taken to a wildlife centre.

Officials estimated Bing's weight to be around 250kg - more than double the average weight of an American black bear which usualy weight 110kg

Footage shows ten wildlife workers carrying Bing from his home at the Wat Luang Phor Lamai temple in Phetchabun province, Thailand, and loading him into a truck
